The MIPI Alliance has released MIPI CSI-2 v2.0, an update to its MIPI Camera Serial Interface (CSI-2) specification. The release expands the applicability to open up more opportunities for innovation on the architecture. According to MIPI, designers will be able to extend their product lines to target imaging and vision needs for mobile, the Internet of Things (IoT), wearables, medical, augmented and virtual reality, drones and automotive systems.

CSI-2 v2.0 can be implemented on either of two physical layers from MIPI Alliance: MIPI C-PHY and MIPI D-PHY. Both physical layer specifications have been updated to support the new CSI-2 v2.0, allowing designers to take advantage of the latest enhancements while supporting backwards compatibility.

Expanded virtual channels from 4 to 32 to accommodate the proliferation of image sensors with multiple data types and support multi-exposure and multi-range sensor fusion for Advanced Driver Assistance Systems (ADAS) applications such as enhanced collision avoidance

Latency Reduction and Transport Efficiency (LRTE) provides increased image sensor aggregation without adding to system cost; facilitates real-time perception, processing and decision-making; and optimizes transport to reduce the number of wires, toggle rate and power consumption
